9 Communication Interfaces
The UPS is factory-equipped with RS232 and USB Communication Interfaces. On the UPS rear side there are the
connections of the Interfaces.
Only one of the RS232/USB communications can be activated at one time. To activate RS232 communication it is
sufficient to connect the RS232 cable only; to activate USB communication it is sufficient to connect the USB cable
only.
It is possible to use a SNMP (Single Network Management Protocol) Interface to connect the UPS to a LAN (Local
Area Network). The SNMP interface is optional.
We advise you to follow the steps below explained to install the interface correctly:
1. Remove the metallic panel (#4, figure 4) that covers the slot for SNMP interface.
2. Put the SNMP Interface into the slot and fix it with screws.
3. Connect the LAN cable to SNMP interface and follow the included instruction to make the interface working
well.
